Equipment and method for producing nano metal powder

The invention relates to the technical field of metal powder production, and particularly discloses nano metal powder production equipment and a method thereof.The nano metal powder production equipment comprises an evaporation chamber, at least two arc generators are installed in the evaporation chamber, and each arc generator is provided with a surrounding air channel; the distance between an air outlet of the surrounding air channel and the arc excitation ends of the arc generators is 10-100 mm, the jet velocity of the air outlet of the surrounding air channel is 5-10 m/s, cooling air channels are formed in the evaporation cavity, and the number of the cooling air channels is consistent with that of the arc generators. Related parameters of the surrounding air channel are controlled, it is guaranteed that the multiple arc generators can stably excite the high-temperature plasma arc, and the yield of the nano metal powder is increased. And meanwhile, under the combined action of surrounding air and cooling
